The Prince of Wales has arrived at the hospital where his father the Duke of Edinburgh remains after feeling unwell.

Philip was admitted to King Edward VII’s hospital in London on Tuesday evening as a precautionary measure and walked unaided into the medical centre.

Charles arrived at the hospital at around 3.20pm on Saturday in a grey Tesla car, and exited the vehicle wearing a face mask.

He is the first member of the royal family to visit Philip during the duke’s four-night stay in hospital.

The duke, who turns 100 on June 10, is in hospital for an undisclosed reason, although it is not coronavirus-related.

On Friday, sources told PA news agency: “Following consultation with his doctor the Duke of Edinburgh is likely to remain in hospital for observation and rest over the weekend and into next week.

“As we have said previously the doctor is acting with an abundance of caution. The duke remains in good spirits.”

Earlier in the afternoon, 10-year-old Twanna Saleh, from Camden, north London, wished the duke a “quick recovery” outside the hospital with a home-made sign.

Twanna said: “When I was little I used to have chemotherapy for five years and I felt sad for Philip so I wrote this letter so he can feel better.

“My sister helped me to draw the heart and the flower.”
